The tracks made for the model
included a crop circle in a field to the north.

A nine minute video documentary about the model making process was produced
in June 2005. It includes footage captured at the site and animations
of the GPS tracks alongside time-lapse footage of the model being constructed.

The location of the White Horse in Uffington was chosen for its intricate
terrain formed from the steep chalk downs, and for its distinct features
that have been shaped by man since the Bronze Age. We first mapped White Horse Hill with GPS receivers in 2001. In 2002 we did it again to make a 1:1000 scale
model from our tracks.

The model displaces our trajectories by a transferral of
surfaces. It is a three-dimensional map of our systems of movement within
43 kilometres of walks made over four days. We acted as data collectors
by traversing the area in order to generate the material to model the
experience.

Our GPS tracks were processed and reduced in scale by
1000 times and printed as templates on cardboard sheets. They included
a plan view of the journey (track position), and many strips of various
lengths (distance) and widths (altitude). On each strip were score-lines
with colours that indicated the varying degrees of change in the direction
of the track.

The GPS model was created as a physical reference to a history of geograms
that can be traced back to the Nasca Lines made in Ancient Peru and the
chalk figures carved into the English landscape. In both cases they were
made by either clearing a path by the removal of stones or of topsoil
over large areas. They revealed signs, not entirely visible from the ground,
projected towards the skies like symbols on a map to be seen by the gods.
